Tip: You can be specific about the time to fast-forward or rewind, such as saying "Alexa, Rewind 8 seconds." This is helpful if you missed what a person says on a video and you want to rewind a few seconds to hear it again.

Scope of the Alexa Integration

Internally, Fire App Builder uses Android Media Session methods to get the control commands from Alexa. The interactive voice commands are applicable when watching and playing media. (The Alexa integration in Fire App Builder does not use the Video Skills API.)

Note that the Alexa commands cannot surface specific media titles within your app through voice search. For example, you can't say "Alexa, play Gizmo movie" (or whatever your content might be called). Voice search for your app's content is only possible when you integrate your media into the Amazon Catalog.

However, if you've linked your Echo to your Fire TV, you can say "Launch the {Name of App} App" and the app will launch. However, this integration is not specific to Fire App Builder and works will all apps.

Disable Alexa Support

If you want to disable media session support (so that no voice interactivity with content is available), open your AndroidManifest.xml file (in app > manifests) and comment out this permission:

Note that if you're updating an existing app by adding this permission to your manifest, your app will not automatically update. Users who already have the app installed will need to explicitly give permissions to install the update. Afterwards, users with the installed app will get automatic updates as usual.
